Etymology: Characidium: Diminutive of Charax, -akos = a fish without identification (Ref. 45335); summum: From the Latin summus, which means high, elevated, alluding to the high altitude where the species occurs, near Pico Tracoá, higher than 1100 m above sea level in the Serra dos Pacaás Novos (Ref. 104900).

Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 11 - 13; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 8 - 9; позвонки: 36. Diagnosis: Characidium summus is a unique species among congeners by lacking an adipose fin and having a complete lateral line; can be further distinguished from congeners, including C. vestigipinne, that have complete lateral line and adipose fin absent, vestigial or reduced by the absence of dark bars or spots on head, body or fins, except for a dark blotch immediately on the rear of opercle, a narrow midlateral dark stripe (less than half scale deep), and a dark basicaudal spot (Ref. 104900).

The rio Pacaás Novos is a black water river, with moderate water current and predominantly rocky bottom; specimens of C. summus were sampled in small puddles (1-4 m wide and 1.5 m deep) and laterally in the river backwaters (Ref. 104900).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
